Hi,
ASME BPVC VIII-1 considers only the case of opening within 80% of diameter. what about opening outside this area?
For Hillside opening in cylindrical shell, reinforcements parallel and perpendicular to the longitudinal axis analysis are required. There is nothing regarding Hillside opening...
APPENDIX 13
units mismatch
13-7 paragraph for example.
Equation (1) unit of Sm = [P]*[h]/[t1]=psi*in/in=psi
Equation (3) unit of (Sb)N =([P][c]/[I1])[H^2]=(psi*in/in^4)*in^2=psi/in
as it is a stress it shall be in psi.
so what is wrong?

I see that the reducing flange are allowed according to ASME B16.5. for example you can have a face of 10'' Class 150 and a hub of 2''. But i'm wondering if it's allowed to be used with design according to ASME B31.3. I think stress analysis should be made. What are your thoughts ?
